*if* I'm not sure they will even though that's the plan. If you look
in the libressl overlay, you'll see lots of patches to make big ticket
items like apache play nice with libressl. These patches involve things
like
+#ifndef HAVE_SSL_CTX_USE_CERTIFICATE_CHAIN
int SSL_CTX_use_certificate_chain(SSL_CTX *, char *, int,
pem_password_cb *);
+#else
+ int _SSL_CTX_use_certificate_chain(SSL_CTX *, char *, int,
pem_password_cb *);
+#endif
which points to the differences in functions are being exported by the
two. This makes me lean towards a USE flag which can also be tied to
applying patches rather than a virtual which is better suited for simple
drop in substitutions.
